#caedemon

As Huanglongmon's creations and members of the Archangels, both of them served them and the four Great Beasts as guardians of their world, alongside the other eight of their kind. For thousands of years, they were the guiding light for all the other Digimon to look up to, until Lucemon's betrayal, and the other six Archangels siding with him. Having discovered what would later become known as the Dark Area - an eldritch, mysterious and volatile dimension existing apart from the Digital and human worlds, yet intertwined with them - he chose to keep it secret, and, in time, his own desires, made worse by the influence of the Area, made him turn against his world and creators. The six others that succumbed to it all the same chose to follow their leader, and nearly laid waste to the Digital World by breaching the dimensional walls and unleashing the Area upon it, but were ultimately stopped by the remaining three Archangels, the world's inhabitants, and Huanglongmon's ultimate sacrifice to seal the Dark Area away, along with the traitors.

Ophanimon perished in those battles, but was reborn in the far future, though without memories of her past.

It was the actions of mankind that called her to action once more, and what awakened Caedemon from his eternal slumber deep within the Dark Area. It was when humans, upon discovering its existence, breached it in an attempt to take control of its powers and Caedemon himself - and sealed the fate of both worlds.

Caedemon, like his brethren, was never meant to be awakened, and Tailmon was mortified upon eventually figuring out the identity of the decaying beast. In her eyes, rightfully, not only was he a traitor, but also even alone a serious danger to both worlds, having become part of the Dark Area itself, but he was also absolutely not fit to be a Tamer's Digimon, especially to a child.

Caedemon initially also did little to soothe her concerns, even with her disdain and suspicions for him obvious, as he exhibited a selfish, troubled and nihilistic personality, caring little for their own kind, and consistently questioning whether or not humanity is even worth saving, with all they've learned about it - a big contrast to her more optimistic outlook on things, a love for all living beings, and a desire to seek out good in everyone, even to the detriment of herself and others.
